If you’ve presented or viewed posters, you’ve probably noticed there’s a lot of stuff on them that don’t really matter.
We put them on because we want to mimic scientific papers. References are a great example. Several of my colleagues are of the opinion that any academic work without a reference list is unacceptable. Listening to some, you’d think that such a poster would cause the conference hall to explode and leave every molecule in your body streaming away from the center of the blast at near the speed of light.
So we cave. We stick on a terminal reference list in Harvard format that nobody looks at. It might be shorter than the one in the published paper, but few dare to cut it entirely.
